Marantz PM-11S1

The pre- main amplifier that it succeeded the technology of separateamplifier SC7S1of 2002 April sale andMA9S1.

 As for rated output 100W×2ch (8 Ω), 200W×2ch (4 Ω).

Front design was renovated from this time, "new premium design" was adopted. 

It consists front panel and the aluminum side panel of aluminum 3 piece structure, furthermore radiates portion of front panel to the blue, 

it is basic concept that "it is not restricted by just shape and arrangement and from it requested" the expression with light "".

"HDAM SA2" of new development was adopted to the amplifier. 

Being something which evolved the high-speed voltage amplification module "HDAM SA" which is adopted for SC-7S1,

 you adopt for the buffer amplifier and the like of electric current feedback system.

 The line buffer which used private HDAM SA2 in all line input is loaded.

The volume amplifier combined "WM8816" of England Wolfson and HDAM SA2. You say that you connected WM8816 in parallel,

 improved Signal-noise ratio. Combining HDAM and HDAM SA2, it becomes same company first electric current return type .

As for the power amplifier section, the voltage amplifier (the voltage amplification circuit) 10.5dB,

 the power buffer amplifier (the power amplification circuit) adopting 2 amplifier constitution of 12.5dB. 

Influence of back electromotive force from the speaker is decreased.

In addition, you say that instantaneous current supply source ability former ratio 2 time 

was raised the power source section/the power block section the pole of baseplate foil thick, OFC of impedance conversion and 70 μ m

 with the power source wiring material and the second look etc. at internal layout low thickly. The power transistor adopts same ones as MA-9S1.

Adopting choke input type power source for the power circuit of the pre-amp step. 

We have assumed that the harmonic which become cause of noise are removed. 

Furthermore, you say that super ring large-sized toroidal trance, bulk low you adopted Chemical Condenser and the Schottky barrier diode etc. 

of impedance foil magnification ratio low, power source served low in impedance conversion.

The maximum of 4 units (channel 8) PM-11S1 can be connected "F.C.B.S. (floating control bus system)" to load, 

it corresponds to the sink control of each machine. To pre- main F.C.B.S. As for being loaded the first time. SC-7S1 could do the sink control maximum of 6.

As for maximum external size 440×444×162mm (width × depth × height), 

as for weight 26kg. Output 200W×2ch (at the time of 4 Ω load) as for electric power consumption 880W

PM-11S1 similarly, the luminous system was provided for front panel, the SACD/CD player who adopts "new premium design".

 Loading the same company original mechanic module. DAC "SM5866S" of the NPC corporation that is loaded 2 it was optimized in SACD.

The individual which uses 24bit DSP "PEC (Phase Error Compensation)" loading the circuit. You say that flat it does not have around the phase quality was actualized.

 In addition, we have assumed that by the fact that crystal リクロック of the data by the master clock is done, clock precision was raised. As for crystal precision ±5ppm.

Adopting HDAM to IV converting circuit and the low-pass filter. HDAM of electric current return type is loaded to the output circuit.

As for the digital filter change of 3 modes is possible. At the time of CD playback, DC filter ON/OFF, the noise shaper - it can select also ON/OFF.

In addition, you adopt the XLR terminal of full balance type for analog output, similar to audio output, consist the electric current return type HDAM circuit.

 Also optical digital output and coaxial digital output have. As for external size of substance 440×418×123mm (width × depth × height), as for weight 14kg.
